VAPORIZ'ING-TUBE.

SPECIFICATION formingpart of Letters Patent No. 635,554, dated October 24, 1899.

Application filed January 23,1899- Serial No. 703,197. (No model.)

T at whom it may concern:

Be it known that I, ARTHUR KITSON, a subj ect of the Queen of Great Britain, and a resident of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Vapori-zing- Tubes, of which the following is a specification.

My invention relates to vapor-burning apparatus, and is specifically designed to produce an improved form of vaporizing-tube.

One difficulty encountered in the use of vapor-burning apparatus inwhich the heat of the burner vaporizes the oil in the vaporizingtube or other chamber is that when poor grades of oil are used a considerable quantity of carbon or other solid material is deposited in the vaporizing-tube and getting into the discharge-orifice interferes with the discharge of the vapor and the even operation of the lamp. My present invention presents one method of overcoming this difficulty; and it consists, broadly stated, in making the vaporizing-tube in two sections connected and communicating, the lower section being arranged horizontally and connected with the oil-supply, while the upper section has the discharge-openin g for the jet formed therein. Thus all the carbon and other solid matter is deposited in the lower section of the tube, where it does little or no injury, and none gets into the upper section and cannot, conse quently, reach the orifice through which the vapor-jet is discharged.

The preferred form of apparatus embodying my invention is illustrated in the accompanying sheet of drawings, in which- Figure l is a central section of the operative portion of the vapor-burning lamp with my improved vaporizing-tube in position.

Fig. 2 is a detail end view showing'the vapo-.

rizing-tube and shutter for closing the opening through which it is withdrawn.

Throughout the drawings like referencefigures refer to like parts.

The parts of the vapor-burning lamp shown are the chimney 1, the reflector 2, mixing-tube 3, and the burners 4, preferably having the incandescent mantles 5 over them. The lamp is suspended from the hanging rod 6 and has I the heat-shield 7. The mixing-tube has an enlarged month 8, in which may be located the injector-cone 9, if desired.

The vaporizing-tube is composed of the lower and longer section 10 and of the upper and shorter section 11, whose ends overlap. At the overlapping portions the two sections are fastened together bybrazin g or otherwise, and one or more passage-ways 12 and 13 afford communication between the two sections. These passage-ways are preferably made small, as shown. The section 11 has the discharge-opening 14 for the vapor-jet, which is opposite the mouth of the mixing-tube. The section 11 may also have a notched feather 15 on it, with which the ring 16 engages to hold the vaporizing-tube in proper position with relation to the mixing-tube. Gauze diaphragms 12 and 13 are arranged in the shorter section 11 of the vaporizingtube, between the openings 12 and 13 and the discharge-opening 14. A third wire-gauze diaphragm 14: may also be placed in front of the discharge-orifice 14.

The shorter section 11 of the vaporizingtube projects through an opening 17, made for it in the wall of the chimney, and in the opposite wall of the chimney is an oblong opening 18, through which the two sections of the vaporizing-tube may be withdrawn. When the vaporizing-tube is in position, the opening 18 is closed around the single section of vaporizing-tube within, extending through the opening 18, by sliding down the shutter 19. (Shown in Fig. 2.)

20 represents the oil-supply pipe, connected to the end of the vaporizing-tube in any wellknown way.

The method of operation of my invention is as follows: The parts being shown as in Fig. 1, when the oil is turned on it is vaporized in the longer section 10 of the vaporizing-tube which is within the heating zone of the burner or burners. Any solid carbon or other solid material in the oil is deposited in this section and cakes along the wall of it without materially interfering with the operation of the apparatus. The vapor passes up through the openings 12 and 13 and through the gauzes 12 13 14:, so that every solid impurity is necessarily left behind by the time it reaches the discharge-openin g 14. The jet passes through the cone 9 down the mixingtube, supplying the necessary volume of mixed air and vapor to the burners in the well-known manner. All solid material havin g been eliminated in the manner described, the lamp will continue to burn, even on a poor quality of oil, for several hundred hours without the discharge-opening clogging up. \Vhen the tube is to be withdrawn, the shutter 19 is lifted and the ring 16 and the tube pulled out to the left. (See Fig. 1.)

The advantage of my invention consists in its eliminating the difficulty of clogging up the jet-openin g, as above described.

Various changes could be made in the relative proportions of the parts of the apparatus and in their details of construction, evidently, without departing from the spirit and scope of my invention so long as the principle of operation above described is preserved.

Having therefore described my invention, what I claim as new, and desire to protect by Letters Patent, is-- 1. A vaporizing apparatus comprising a longer horizontal section and a shorter horizontal section, their ends overlapping, and having one or more openings through the adjacent walls of said section, the dischargeopening of said vaporizing apparatus being in said shorter section, together with one or more gauze diaphragms located between said discharge-opening and the openings between the two sections.

2. In a vapor-burning apparatus the combination of the vapor-burner, the chimney over the same, the mixing-tube at one side of the chimney and extending down to the burner, the vaporizing-tube composed of two sections not in line one with the other, but connected together, a circular opening in the side of the chimney adjacent to the mixingtube, through which opening one section of the vaporizing-tube extends, and an oblong opening inthe other side of the chimney through which the entire vaporizing-tube may be Withdrawn.

3. In a vapor-burning apparatus the combination of the vapor-burner, the chimney over the same, the mixing-tube at one side of the chimney and extending down to the burner, the vaporizing-tube composed of two sections not in line one with the other, but connected together, a circular opening in the side of the chimney adjacent to the mixing-tube,

through which opening one section of the vap= orizing-tube extends, and an oblong opening in the other side of the chimney through which the entire vaporizing-tube may be withdrawn, together with the shutter which closes said oblong opening when the vaporizing-tube is in position.

Signed by me at Philadelphia, Pennsyl Vania, this 14th day of January, 1899.
